2016-07-14objcopy/strip: Allow section patterns starting with '!'.Andrew Burgess8-11/+124
For symbol matching, prefixing a pattern with '!' will indicate a non-matching pattern, however, this is not the case for section patterns. As a result it is not possible to say "apply this action to all sections except ...". With this commit the objcopy and strip tools now support '!' prefix for section patterns, so we can say: objcopy --remove-section="*" --remove-section="!.text*" Which will remove all sections, except those matching the pattern '.text*'. binutils/ChangeLog: * objcopy.c (find_section_list): Handle section patterns starting with '!' being a non-matching pattern. * doc/binutils.texi (objcopy): Give example of using '!' with --remove-section and --only-section. (strip): Give example of using '!' with --remove-section. * testsuite/binutils-all/data-sections.s: New file. * testsuite/binutils-all/only-section-01.d: New file. * testsuite/binutils-all/remove-section-01.d: New file. * testsuite/binutils-all/objcopy.exp: Run new tests. * NEWS: Mention new feature.

2016-06-24MIPS objcopy --rename-section fixAlan Modra6-38/+74
Some MIPS targets use a named section symbol rather than a symbol with no name as is used with most ELF targets. When renaming sections, the named section symbol needs to be renamed too. Rather than fix this bug, I'd originally intended to just correct the xfail added recently for update-1.o vs update4.o in update-section.exp, using the same set of targets for the localize-hidden-1 mips xfail. I'd extracted that target test into a new function, is_bad_symtab. It turns out to be useful in readelf.exp too. bfd/ * config.bfd: Delete mips vxworks patterns matched earlier. Combine mips*-*-none with mips*-*-elf*. binutils/ * objcopy.c (find_section_rename): Forward declare. Remove ibfd and sec_ptr param. Add old_name param. Allow for NULL returned_flags.

2016-05-25Enable 64-bit archives in ar and ranlibH.J. Lu2-0/+8
Since existing ld and gold support the 64-bit (MIPS) ELF archives, we can use the 64-bit (MIPS) ELF archives as 64-bit archives. Since the plugin target is used to create archive in plugin-enabled ar, we need a way to enable 64-bit archives in the plugin target. This patch adds --enable-64-bit-archive to bfd to force 64-bit archives in ar and ranlib. Since both 64-bit MIPS and s390 ELF targets currently use 64-bit archives, 64-bit archives are enabled by default for them. 64-bit archive is generated automatically if the archive is too big.

Mixing MIPS16 and microMIPS code in a single binary isn't usually supported but GAS happily produces such code if requested. However it is not correctly disassembled even if a symbol table is available and function symbols are correctly anotated with the ISA mode. This is because the ELF-header global microMIPS ASE flag takes precedence over MIPS16 function annotation, causing them to be treated as regular MIPS code. Correct the problem by respecting function symbol anotation regardless of the ELF-header flag. binutils/ * testsuite/binutils-all/mips/mixed-mips16-micromips.d: New test. * testsuite/binutils-all/mips/mixed-mips16-micromips.s: New test source. * testsuite/binutils-all/mips/mips.exp: Run the new test. opcodes/ * mips-dis.c (is_compressed_mode_p): Add `micromips_p' operand, replacing references to `micromips_ase' throughout.

2016-05-16V850/BFD: Call `_bfd_elf_copy_private_bfd_data' againMaciej W. Rozycki2-2/+5
Correct a regression introduced with commit 685080f21003 ("Adds support for generating notes in V850 binaries.") which replaced rather than extending the call to `_bfd_elf_copy_private_bfd_data' with `v850_elf_copy_private_bfd_data'.

(v850_elf_copy_private_bfd_data): ... here. Call the new function and `_bfd_elf_copy_private_bfd_data'. binutils/ * testsuite/binutils-all/objcopy.exp: Don't skip the `strip-10' test for the V850.
